Austin is different from many cities: its own list of work that does not need a building permit includes replacing asphalt shingles. That does not mean every roof job is exempt, and it does not mean the work is free of code rules. Here is what the city's list says, where the exceptions are, and what to ask a roofer before you sign.
Short answer: the city lists replacing existing asphalt shingles, and replacing any roof covering that does not adversely affect the roof structure, as work that does not need a building permit. The exception is a property in the Wildland-Urban Interface area when 50% or more of the roofing is being replaced.
What Austin's Exempt-Work List Says
The City of Austin Development Services Department publishes a list of work that is exempt from a building permit. For residential roofing, these items are on that list:
- Replacing existing asphalt shingles, unless the property is in the Wildland-Urban Interface area and 50% or more of the roofing is being replaced.
- Replacing any other roof covering that does not adversely affect the roof structure, with the same Wildland-Urban Interface exception.
- Roof decking that does not exceed 128 square feet.
- Repairing or replacing exterior trim, including wood fascia, trim and soffits.
The same page says exempt work "must still comply with applicable Building Codes, City Codes, and all other applicable ordinances." In other words, no permit does not mean no rules.
⚠️ The exception that matters: if your home is in the Wildland-Urban Interface area and half or more of the roof is being replaced, the exemption does not apply and a permit appears to be required. Ask the city whether your address is in that area before you assume you are exempt.
When the Job Goes Beyond the Exemption
The exemptions are about replacing the roof covering. Work that changes the structure is a different conversation: the decking exemption stops at 128 square feet, and a covering replacement is exempt only when it does not adversely affect the roof structure. If your roofer finds rotted decking or wants to change framing, ask whether that moves the job outside the exemption.
What to Ask Your Roofer
- "Is this address in the Wildland-Urban Interface area, and are you replacing 50% or more of the roof?"
- "Do you expect any decking or structural repair, and how many square feet?"
- "If a permit is required, who pulls it and is it included in the written estimate?"
- "Can I have the scope of work in writing, including what was replaced?"
Who to Call
Austin Development Services answers permit questions at 512-978-4000 during business hours, and Austin 3-1-1 after hours. The city also has a "Check if you need a permit" tool on its website. A five-minute call costs nothing and settles it for your specific address.
A fair warning about other websites: many roofing sites say a permit is "always" or "never" needed in Austin. The city's own list is more specific than either: it depends on the material, how much of the roof, the structure, and where the property is.
